A modified polyurethane resin comprising a molecular chain represented by the following general formula (I) and an adhesive composition comprising the same. [Chemical Formula 1] (I) (In the formula, X represents a divalent organic group containing an aromatic ring or an aliphatic ring; Y represents a divalent organic group with a molecular weight between 100 and 10000; Z represents a (4-r)-valent organic group having 4 or more carbon atoms; R represents a reactive group; r represents an integer of 0 to 2; and n and m each independently represents an integer of 1 to 100. A plurality of X, Y, Z, and R in the same molecule may be the same or different, respectively. However, at least one R is present in the molecular chain.) |
